Question about startup messages after uninstalling nVidia ..

I recently replaced my TNT2 M64 Video card that came with my Dell
Dimension 4100 with an ATI 9600 Pro. I followed the installation steps
and uninstalled the nVidia drivers, turned off the computer, installed
the ATI card, rebooted and then installed the ATI drivers. After
uninstalling the nVidia drivers I have been seeing the following at
startup that I don't remember seeing before:

Windows Expanded Memory Driver 4.95
Copyright 1988-1995 Microsoft Corporation

EMM386 not installed -- unable to set page frame base address

Total upper memory available ... 66KB
Largest upper memory block ... 59KB
Upper memory starting address... CD00 H

EMM386 Active

Is that normal? What does it mean? Do I care?

I am running Windows 98SE on a Dell Dimension 4100 (P3, 933 MHz).

Thanks,
